f(x) = 10x - 6\ln(x), x > 0.
(A) List all critical numbers of f. If there are no critical values, enter 'NONE'.
Critical numbers =
(B) Use interval notation to indicate where f(x) is increasing.
Note: Use 'INF' for ?, '-INF' for -?, and use 'U' for the union symbol.
Increasing:
(C) Use interval notation to indicate where f(x) is decreasing.
Decreasing:
(D) List the x-coordinates of all local maxima of f. If there are no local maxima, enter
'NONE'.
x values of local maxima =
